Wire management grommet with non-captive closure member

ABSTRACT

This invention relates to a two-piece grommet adapted for holding a cable in an aperture, such as in a desk or work surface so as to absorb any strain imposed on the cable and to provide an attractive covering for the hole drilled to pass the cable. The grommet consists of two portions. The first portion comprises a cylindrical sleeve having a circular lip. The second portion comprises a cap having an extended flange and adapted to frictionally fit into the cylindrical sleeve and against the lip. The cap has an aperture cut into it through which the cable passes. A pivotal tab is connected under the cap to close the aperture when no cable passes therethrough.

BACKGROUND OF THE INVENTION

Devices for passing a flexible non-flexible cord, such as a telephonecord or computer cable, through one or more elements such as a desk top,a piece of furniture, a wall or other type of installation are wellknown. Various devices to do this are known in the art and each of thesedevices has drawbacks. One device, which is now being used, requires aspring loaded cap which is held in place within a sleeve by the actionof the spring. This device is complex, expensive and difficult to use.Other devices consist simply of a cylindrical sleeve in which the holein the panel or desk must be cut to precisely the exact size or thesleeve will simply fall out, particularly if it is set in a verticalposition. If the hole is not cut to the precise size, means must be usedto secure the sleeve into the hole.

OBJECTS OF THE INVENTION

It is an object of the present invention to provide a simple, improveddevice for passing a cable or cord through an aperture in a work surfacesecuring the cord.

It is still a further object of the invention to provide a grommetcapable of being held easily in a hole cut into a work surface, forpassing an electrical cord.

Still a further object of the invention is to provide a grommet forholding an electrical cord which can be easily held and used in both avertical and horizontal position.

Still a further object of the invention is to provide a means to closethe hole when not in use.

These and other objects will be described by reference to theaccompanying drawing in which:

FIG. 1 is a perspective view of the grommet assembly of the presentinvention.

FIG. 2 is a perspective view of the bottom of the cap portion of thepresent invention, and

FIG. 3 is a side view partially broken away of the cap portion of thegrommet of the present invention.

Referring now to the drawings, there is shown the sleeve portion 10 ofthe grommet of the present invention and the cap portion 12. The sleeveportion comprises a cylindrical hollow sleeve 14, and a lip 16 having alarger diameter than sleeve 14. Sleeve 14 optionally has a rib 18slightly raised from the surface of sleeve 14. The cap portion of thegrommet of the present invention comprises a shank portion 20 and aflange or lip portion 22. Cut into the cap 12 is an aperture or slot 24through which will pass the electrical cable 36 which is held by thegrommet of the present invention.

The shank portion 20 of the cap is of a diameter substantially equal tothe inner diameter of the sleeve portion 10 so that the cap frictionallyfits and is held in the sleeve portion 10. The flange 22 rests againstlip 16.

A tab 26 is pivotably attached to the underside 28 of cap 12. Tab 26 isshaped so that it frictionally fits into slot 24. Thus, when no cable ispassing through slot 24, tab 26 can be closed so that no opening appearsin the cap 12 and it appears to be a solid surface. Tab 26 fits tightlyenough frictionally so that it stays in place in slot 24 until pusheddown to reopen slot 24.

Tab 26 has a connecting arm 30 which has a male connector comprising anelongated cylinder 32 at the end thereof. Cylinder 32 snap fits into afemale receiver portion 34 which holds cylinder 32 yet allows it topivot. Cylinder 32 can be pulled, with mild force, out of receiverportion 34 so that tab 26 can be separated from cap 12, if desired, andreplaced when needed. Thus, this design allows the user to swing tab 26down and out of the way if desired or it can be removed entirely.

Arm 30 is attached under tab 28 creating a step 37. Step 37 is necessaryto pivot tab 28 so that it is flush with the top surface of cap 12 whilearm 30 remains underneath cap 12 and out of the way.

In using the device of the present invention, a hole is drilled or cutinto the panel, wall, board, desk or work surface 25 through which theelectrical cable 36 is to pass. The sleeve portion 10 of the presentinvention is then pressed into place in the hole with rib 18 forming ameans for the sleeve portion 10 to be frictionally held in place even ifit is in a vertical direction. The rib 18 also provides a means to holdthe sleeve in place if the hole has not been drilled precisely to thecorrect size and is slightly too big. Rib 18 also acts as a dam to holdglue if it is desired to glue sleeve 10 in place.

The electrical cable 36 is then passed through the hole in the panel,wall, desk or work surface which now contains sleeve 10, and then cap12, with tab 26 pivoted down and out of the way, is placed over thecable and pressed into place, so that shank 20 frictionally fits intoand is held in the inside diameter of the sleeve 10.

The aperture 24 that is cut into the cap 12 can be made of a variety ofsizes and shapes depending upon the size of the electrical cable to bepassed through the grommet or the size of the hole in the desk. Tab 26,of course, must conform to the size and shape of aperture 24.

The lip 16 of sleeve portion 10 will rest on the flat portion of thewall, panel, desk or work surface, holding the sleeve portion 10 inplace, so that it will not fall through the hole. The rib 16 willprevent the grommet from slipping back and forth within the hole inwhich it is placed.

An additional advantage of the lip 16 and the cap 22 is the fact thatwhen holes are cut into walls or desks there are usually rough edges orchips in the wood, and lip portion 16 will cover these unsightly chips.On steel or metal surfaces, the grommet prevents cutting of the cable bya rough metal edge.

Referring specifically to FIG. 3, there is clearly shown a 90 degreeangle between the sleeve 14 and the lip 16. This 90 degree angle allowsthe lip 16 to rest on the surface of the work surface.

In addition, there is shown a beveled edge 38 on cap 12. The bevelededge 38 not only is aesthetic but will allow the sliding of objects overthe top of cap 12 with very little resistance.

The grommet of the present invention can be made of any convenientmaterial, such as plastic, metal, or wood, but is preferably made ofplastic since it is easiest to produce and also is a non-conductivematerial in the event of any electrical cables which may have a problemof shorting or shocking a potential user.

The grommet of this invention also has the adaptability that the sleeveportion 10 can be used without the cap portion 12 in the event any cableor cables must be passed through the hole that fill the entire insidediameter.

In additions two sleeve portions 10 can be placed back to back to coverboth the top and bottom or both sides of a hole in a work surface orwall. Caps 12 can be placed on one or both sides.
